The invention relates to cop winding machines of the kind having mechanism whereby cop tubes are placed on a plurality of spindles simultaneously, and whereby the cops are also taken oil the said spindles simultaneously. In some machines this mechanism includes an endless conveyor working on pulleys, wheels or drums with horizontal axes, the conveyor serving to carry the tubes to the bank of spindles, and in some cases to carry away the cops.

In our invention we also use an endless conveyor, but we arrange the same so that it travels round the machine in a' horizontal plane, that is to say it works on pulleys, wheels or drums having vertical axes, and we use this conveyor to carry holders for the cop tubes to be supplied to the spindles, and in some cases also holders for the cops taken from the spindles.

The tube holders and the cop holders may be pivoted to the conveyor, mechanism-being provided for swingingthem into position for delivering tubes or receiving cops, and then allowing them to swing back.

The cop holders may have clips which engage the cops and subsequently, in the course of the travel of the conveyor, strike an abutment whereby they are opened and caused to release the cops.

Where yarns oi diflferent kinds or diflerent colors are wound on the same machine we may arrange the mechanism so that these are automatically sorted on delivery of the cops, there being a separate receptacle for each color or kind of yarn, with an abutment placed at a different level over each receptacle, the cop holders being divided into groups having clips disposed respec- .tively at levels corresponding to those of the abutments, so that each group will deliver to one particular receptacle. Two embodiments of the invention are illustrated in the accomp yin drawings, in Fig. 1, and Figs. 2 and 3 respectively.

In the drawings, Fig. 1 is a sectional view of the machine, with certain parts in elevation,

Fig. 2 is a sectional view of a second embodiment of the machine, with certain parts in elealigned with the spindles 2|. 'Ihe tube holders 36 are provided with spring clips 36b for engaging the tubes. For swinging the cop tube holders 36 there is a lever mechanism comprising a rod I50 extending along the bank oi spindles and car- 5 ried by arms I52 pivoted to the frame of the machine at iii. The rod I50 can be swung up and down by means 01' a handle I 52a.

For domng and donning the cops and tubes. there are provided rack bars la, 01' which only 10 one is visible in the drawing, upon which are mounted two angle bars 34a and 34b spaced apart a little more than the length of the cop tube. The rack bars a are guided in bearings 22 and 23 and their teeth engage pinions l5 15 mounted upon a shaft a. This shaft can be rotated in any suitable manner, as by means of a crank (not shown) to slide the bars a in and out.

The operation is as follows: Assuming the 20 spindles to be empty and the parts in the position shown in Fig. 1, while the holders 3. are charged with a set of cop tubes, the handle l52a is swung up to align the tubes with the spindles.

' ward, which causes the cross bar 341: to engage the bases of the cops and slide them off the spindles, so that they drop into a receptacle 52. The 35 bar 341) is provided with notches 33 to allow it to fit the spindles and provide a.well balanced engagement with the bases of. the cops. Meanwhile the tube holders which are next to be brought into charging position have been sup 4 plied with tubes and the conveyor 53 is now started and carries a new set of tubes into position opposite the spindles. Thereupon the tubes are mounted on the spindles as previously described. 45

In the modification shown in Figs. 2' and 3 the tube holders are also swung upwards by means of a rod III, but instead of full length spindles there are stub spindles or Pe s l a, upon which the tubes are held by means of counterpegs 3 carried by a bar fixed to the racks lla. In addition to pivoted holders 3| for the cop tubes the chain carries pivoted holders 5! for the cops. These cop holders I5 alternate with the tube holders 3', the gaps between the holders 55 36 and 55 being equal to halt the pitch of the bank of spindles. The holders 55 are similar to the holders 36, except that their spring clips are of a size suitable for engaging the cops, and each of these clips has an arm 55a with a projecting pin 55b, the purposeoi which will be explained hereinafter.

The chain moves stepwise, the steps being equal to the gaps between consecutive holders I6, 55. When a set of cops has been wound on tubes held by the pegs la and 88 the holders are swung upwards by means of the handle I520, the holders 55 being then in a position to engage the cops. Then the bar carrying the pegs 86 is moved outwards by the rackslla and pinions 45, so that the holders swing down into theposition shown in full lines in Fig. 2. Then I the chain moves a step, and the holders are swung upwards again. By this operation tube holders-36 with empty cop tubes 31 are placed opposite the pegs Ia and the counter pegs 86 are then moved inwards to engage the tubes and push them on to the pegs Ia. Another set of cops is then wound, and so on. The travelling chain carries the cops over a receptacle 68, and the pins 55b, hereinbefore mentioned, strike an abutment I53 in their path above this receptacle, so that the cop clips are opened and drop the cops. In the example illustrated there are additional receptacles 68a and 6822, with abutments 153a and I531) above them, and the abutments I53, I830 and lilb are at different levels. The cop clips are, in this case, also divided into groups, with their pins "b at levels corresponding respectively, to those of the abutments I53, ISM and I531: so that each group of clips will drop its cops into a different receptacle. This arrangement may be adopted where yarns of dif- Ierent colours are being wound, each group of clips receiving cops of a particular colour.

We claim:

1. Ina supply and discharge mechanism for winding machines having a plurality of spindles, an endless conveyor travelling in a horizontal plane and having a fixed position with respect to the winding machine, cop holders and tube holders pivoted on said conveyor to swing in a vertical plane, and means for simultaneously swinging a group of said holders.

2. In a discharge mechanism for winding machines having a plurality of spindles, an endless conveyor travelling in a horizontal plane and having a fixed position with respect to the winding machine, cop holders pivoted on said conveyor to swing in a vertical plane, said holders comprising spring clips, means for simultaneously swinging a group of said holders to receive cops in'said clips, and means for expanding said clips to release the cops.

3. In a discharge mechanism for winding machines having a plurality of spindles, an endless conveyor travelling in a horizontal plane and having a fixed position with respect to the winding machine, cop holders pivoted on said conveyor to swing in a vertical plane, said holders comprising spring clips, means for simultaneously swinging a group of said holders to receive cops in said clips, a collecting receptacle past which said conveyor travels, an abutment adjacent said receptacle, and projections on said clips adapted to engage said abutment to expand said clips and release the cops.

4. In a discharge mechanism for winding machines having a plurality of spindles, and endless conveyor travelling in a horizontal plane and having a fixed position with respect to the 'winding machine, cop holders pivoted on said conveyor to swing in a v'ertical plane, said holders comprising spring clips, means for simultaneously swinging a group of said holders to receive cops in said clips, a plurality of collecting receptacles past which said conveyor travels, a series of abutments stationed adjacent the respcctive receptacles at difierent levels, and projections on said clips positioned so that each projection will engage a-certain-one of said abutments and no other to release the cops into said receptacles according to a classification.
